Wetting and interfacial interaction of molten iron on MgO substrate under different oxygen partial pressures

Effect of Al Content in Steel on Interfacial Interaction between Molten Steel and MgO Substrate

“…At last, high‐purity argon was introduced into the furnace chamber through the deoxygenation tube (JSH‐1), and the flow rate was adjusted to 200 mL min −1 . According to the data from the manufacturer of the deoxygenation tube, the oxygen partial pressure () in the furnace chamber was about 1.87 × 10 −3 Pa. [ 25 ] The furnace was heated up (5 K min −1 ) after the cooling water was turned on. When the steel sample was about to melt, the camera was turned on to capture the image at a frequency of 1 fps.…”
